Border Gateway Protocol (BGP) is the defacto inter-domain routing protocol in the Internet. It was designed without an inherent security mechanism and hence is prone to a number of vulnerabilities which can cause large ...

A Network Operating System (NetOS) is a novel paradigm for developing a next-generation network management and operation platform. As we shall describe, NetOS not only goes far beyond the SDN concepts but also constitutes ...

Optical technologies are the foundations supporting the current telecommunication network backbones due to the high speed transmissions achieved in fiber optical networks. Traditional optical networks consist of a fixed ...

Route leaks are one of the anomalies of inter-domain routing that have the capacity to produce large Internet service disruptions. Route leaks are caused because of violation of routing policies among Autonomous Systems. ...

Providing networks with QoS guarantees is one of the key issues to support current and future expected clients' demands. In this scenario, QoS routing is definitely critical as being responsible for defining those optimal ...

The Path Computation Element (PCE) is positioned nowadays as one of the solutions that almost every carrier will
eventually deploy. The PCE architecture as well as a number of components, including the PCE Communication ...

Internet is becoming a huge heterogeneous and dynamic network that is growing beyond its architectural limits. The scaling up of the number of communicating nodes and services is leading the Internet to an architectural ...

Network performance measurements have been
broadly used in order to debug and to assess the reliability of the network. In general performance measurement is a resource consuming process, which in practice derives in ...

This paper presents a Cross-layer Network Management System (NMS) that allows Service Providers (SPs) to perform cost-effective network resource reservations with their Network Operators (NOs). The novelty of our NMS is ...
